GLOSSARY OF TERMS
POWDER COATING VS SPI
"0" Fire and Smoke Spread Rating Coatings meeting these testing standards will not add to the spread of a flame. At extreme temperatures, they will begin to burn, but will stop when the heat source is removed.
Airless Sprayer A coating sprayer using high-pressure to force a liquid through a nozzle and onto a surface. Spraying provides the most even and consistent surface.
Base and Curing Agent Some coatings require the mixing of two chemicals (a base and a curing agent) to initiate the curing process. All epoxies and some polyurethanes are of this type.
Batt Insulation Includes fiberglass and mineral wool fibre, this is a type of insulation that comes in 'blankets' that are relatively simple to install and provide some R-value.
Ceramic-Based A coating using ceramics as a base material to give certain properties, such as reflectivity and heat blockage.
Chalking Unless UV controlled, many coatings will lose gloss and begin to ‘chalk’ in sunlight. Chalking is the formation of a powder on the surface of a paint film caused by disintegration of the binder during weathering. Epoxy coatings are particularly prone to chalking and must be over-coated, if used outdoors, with a UV controlled coating
Class A Fire Coating Coatings meeting these testing standards will not add to the spread of a flame. At extreme temperatures, they will begin to burn, but will stop when the heat source is removed.
Class A Fire Rating Coatings meeting these testing standards will not add to the spread of a flame. At extreme temperatures, they will begin to burn, but will stop when the heat source is removed.
Condensation Condensation is the accumulation of water on surfaces as a result of temperature differences between the surface and the surrounding air. It is a factor of the temperature difference and the percentage of humidity in the air.
Crosshatch Method A method of spraying on coatings that involves one pass horizontally and then a second pass vertically over the same surface area to ensure complete coverage.
Curing Agent Some coatings require the mixing of two chemicals (a base and a curing agent) to initiate the curing process. All epoxies and some polyurethanes are of this type.
Dew Point The temperature at which air must be cooled to reach saturation and begin to condense. As a surface cools, warm moist air is chilled and water vapour in the air condenses into droplets. The greater the difference between the surface temperature and the dew point, the drier is the air.
Elastomeric The elastic, rubber-like properties of a material that will stretch when pulled and will return relatively quickly to its original shape when released.
Emulsifying To form a suspension of very finely divided oily or resinous liquid in another (watery) liquid.
Enamel A paint that dries to a hard glossy finish. Technically, enamel is a colored varnish or high-gloss paint. Generally, the term is used for high quality, dirt-resistant paints that may have a sheen level from satin to glossy. These coatings are usually used for more demanding applications.
Epoxy A synthetic resin that cures or hardens by chemical reaction between components which are mixed together shortly before use. Epoxy coatings are extremely tough, durable and highly resistant to chemicals, abrasion, moisture and alcohol.
Film Thickness Thickness is usually measured in mils, microns, or millimeters. One mils = one thousand of an inch. The metric equivalent is a micron. One micron = one thousand of a millimeter.
500 mils = ½ of an inch
500 microns = ½ of a millimetre
40 mils = 1 mm
A business card is usually 8-10 mils thick
Hopper Gun Usually air assisted, it is a spray machine used for textured coatings.
Infrared (IR) Light that is so red humans cannot see it. The long wave, electromagnetic radiation of radiant heat emitted by all hot objects. On the electromagnetic spectrum, it can be found between microwave radiation and visible light.
Insulation Equivalent Insulation Equivalent is a system developed to account for all three methods of heat transfer, especially with regard to reflective coatings. The Insulation Equivalent is simply a measure of how well a conventional insulation resists heat transfer through conduction only. The greater the value, the greater the ability of the insulation to resist and absorb conductive heat transfer. The Insulation Equivalent measures the value of a conventional insulation material (i.e. fibreglass or polyurethane foam). The Insulation Equivalent does not consider moisture absorption or air movement.
Intumiscent Coatings designed to expand and swell when contacted with flames, giving a greater volume and area to absorb heat and repel flames.
Latex A water emulsion of a synthetic rubber or plastic obtained by polymerization and used especially in coatings and adhesives. Generally non-toxic and easy to clean up
Metallic-Based A coating using metallics as a base material to give certain properties such as strength, longevity, and flexibility.
Micron and Mils Thickness Thickness is usually measured in mils. One mil = one thousand of an inch. The metric equivalent is a micron. One micron = one thousand of a millimeter.
500 mils = ½ of an inch
500 microns = ½ of a millimetre
40 mils = 1 mm
A business card is usually 8-10 mils thick
Moisture-Cure Coatings that use moisture from the air to maintain the curing process.
Polyurethane Broad class of polymers noted for excellent abrasion and solvent resistance. Can be in solid or cellular form (formed/expanded). Often used as a chemical linkage in finishes, plastic parts and flexible parts. Polyurethane paints are known for their durability.
Polyurethane Foam A type of polyurethane that exists in cellular form. Commonly used as insulation in a sprayed-on or solid panel form.
Pot Life The time after which a two-part (or greater) coating can be applied to a surface, before enough of the chemical curing has occurred to compromise adhesion.
Pot Sprayer An air-assisted hand sprayer using a small container or 'pot' to contain the coating to be applied.
Reefer A refrigerated trailer.
R-Value The R-value is simply a measure of how well traditional insulation resists heat transfer through conduction only. The greater the value, the greater the ability of the insulation to resist and absorb conductive heat. The R-value does not consider moisture absorption or air movement.
Resin Any of a class of solid or semi-solid organic products of natural or synthetic origin, generally of high molecular weight with no definite melting point. The material that forms a hard film on the surface after the chemicals have evaporated. Acrylics and urethanes are the common resins used in water-base finishes.
Saponification A chemical decomposition of a paint's binder from a substrate, by alkali and moisture (e.g., new concrete or fresh plaster). Saponified coatings may deteriorate, lose their adhesion, and become discoloured.
Self-Leveling While curing, self-leveling coatings will spread/even themselves out to a smooth finish, free of brush marks or similar rough spots.
Thermal Shock Thermal shock is the flexing and cracking of concrete due to rapid changes in temperature.
Tip Size The outlet size on a spray gun. Measured in inches or thousands of an inch.
Example: Super Therm® requires a tip size of 0.029-0.032 inches, or 29-32 thousands.
Two-Component Some coatings require the mixing of two chemicals (a base and a curing agent) to initiate the curing process. All epoxies and some polyurethanes are of this type.
Two-Part Some coatings require the mixing of two chemicals (a base and a curing agent) to initiate the curing process. All epoxies and some polyurethanes are of this type.
Urethanes A type of binder used in coatings. Characterized by excellent flexibility, toughness, and chemical resistance.
Ultraviolet (UV) Short wavelength light that is beyond the visible spectrum at the violet end; rays of light that are invisible to the human eye but can damage objects, thus creating the need for UV-controlled coatings for outdoor use.
Ultraviolet (UV) Controlled or Ultraviolet (UV) Protected UV controlled coatings contain components that prevent the breakdown of the coating, due to the damaging effects of UV rays.
Visual Light The portion of the electromagnetic spectrum that can be detected by the human eye. It has a wavelength longer than ultraviolet light and shorter than x-rays.
Visual Wavelength The portion of the electromagnetic spectrum that can be detected by the human eye. It has a wavelength longer than ultraviolet light and shorter than x-rays.
Water-Based or Water-Borne Coatings that use water soluble components as carriers. Are generally easy to use and clean up.

Coatings from Superior Products International II, Inc. provide long-term solutions to previously unsolvable problems. We pride ourselves on developing durable, versatile coatings that outperform the competition. What makes our coatings better? Read for yourself:
The SPI insulation, fire and base coatings are water-based. The corrosion coatings are solvent-based for penetration and durability. The goal is to look at how the surface will be used and then come up with the appropriate coating formula and strength to match the need.
The SPI coatings can be applied to any surface that is clean of dirt, grease, and dust. They can even be applied over existing coatings as long as they are not flaking or loose. Rust Grip® can be coated directly over surface rust and corrosion to seal the surface and is patented to encapsulate asbestos and lead based paints. If any existing coating has a gloss surface, the gloss must be sanded or light-blasted to remove the sheen. The coating does not have to be removed, just the gloss.
The SPI coatings were developed for easy application with a brush, roller, air-assisted sprayer, or airless sprayer. This allows for on location application on parts of any size and shape. The SPI coatings require dry and cure time for optimal performance.
Overspray is always a concern with liquid applied coatings. Although the material cannot be recovered, proper masking of work area will limit the chance of applying the product to unintended surfaces. Clean up for our water-based products is simple, with soap and water being more than sufficient. The solvent-based products require MEK or xylene to remove.
Durability and Longevity
The SPI coatings carry some of the longest-lasting liquid applied systems available. Super Therm® has an expected lifespan in excess of 15 years, and Rust Grip® sets to a 6700 psi surface tensile strength after 3 weeks and gives additional strength and durability to any surface it covers.
Our water-based products are environmentally friendly and do not release solvent emissions. Our solvent-based coatings are formulated to meet environmentally green standards. The SPI Coatings have been certified environmentally safe and eco-effective by MBDC LLC (Gold Certificate) and are approved by the USDA approved for use in and around food preparation areas.
Qualifies for environmental points under the LEED program. SPI is a member of the U.S. Green Building Council.
